The memo directs federal agencies to immediately revoke Krebs’ clearance and suspend those of individuals linked to any entity associated with him—including SentinelOne. This security firm absorbed the Krebs Stamos Group. The order calls for a full-blown review “in the national interest,” it doesn’t stop at clearances.

Trump’s directive demands a comprehensive audit of CISA's activities over the past six years, including any alleged misconduct or unauthorised disclosures of classified information during Krebs’ tenure. The White House accuses Krebs of straying from administration policy on free speech and government neutrality while serving in office.

Krebs, who headed the Cybersecurity and Infrastructure Security Agency from its founding in 2018 until Trump fired him in November 2020, famously contradicted the former president’s fantasy about election fraud, saying the 2020 vote was “the most secure in American history.”

Krebs responded to the move by reposting his 2020 message: “Honoured to serve. We did it right. Defend Today, Secure Tomorrow. #Protect2020.”

Since leaving CISA, Krebs helped launch the Krebs Stamos Group, later folded into SentinelOne. He is now President of PinnacleOne, the firm’s strategic advisory arm.

SentinelOne responded swiftly, saying it would “actively cooperate” with any clearance review and confirmed that fewer than 10 employees would be impacted—only where required under official government rules. The firm doesn't expect “any material impact” on business operations.

“We view the White House as a crucial collaborator on that mission,” the company said, pledging continued work with the US government and its security apparatus to safeguard American infrastructure.

Whether this presidential memo amounts to political retribution or a legitimate audit, it’s clear Trump hasn’t finished settling scores from 2020.
